Misaki, a violin instructor, invites people to "play violin together" and passionately hopes many will enjoy violin for years to come. She carefully tailors lessons and practice methods to each student, from young children to adults. While she loves her work and is doing well, she also carries inner anxieties and loneliness. There are times she craves physical affection. When a student unexpectedly touches her body, her heart wavers. "Ah... I really want a boyfriend..." she finds herself thinking. After three years without a partner, the loneliness becomes overwhelming. Though she takes pride in her role as an instructor, she can't suppress her desire for sex. Meeting a man after so long makes her heart race with excitement. When her sensitive spot is rubbed vigorously, she experiences intense sensations. She becomes wildly aroused when teased with a vibrator, licked all over, tasting a cock, or having her ass licked. When her clit is stimulated by an electric massager while being penetrated by a hard cock, she can't hold back anymore. In such a state, her qualifications as an instructor might even be questioned. Deep down inside, Misaki secretly yearns for sexual fulfillment.
